HI,
Once you have windows defender on you can use the TOOLS section to see what programs load on start up. You may have alot of programs that dont need to start starting up when you turn the pc on.
With out knowing whats in the list its hard to tell you what should not be there.....
a few examples are. Itunes, quicktime, java, adobe reader and downloader, winzip.....
I have taken the below of the microsoft web site.....
Removing Unwanted Programs with Software Explorer
Unwanted programs are not always easy to remove through typical uninstall procedures. In addition, important programs might require components that seem to be unwanted programs. Therefore, Software Explorer enables you to disable potentially unwanted software to test its removal until you feel safe removing it. You can easily restore disabled software if necessary.
To disable or remove unwanted software:
In the toolbar, click the Tools button, and then click Software Explorer.
In the Category menu, select a category to disable or remove.
Select the application to disable or remove.
Click Disable or Remove.
To enable previously disabled software:
In the toolbar, click the Tools button, and then click Software Explorer.
In the Category menu, select a category to enable.
Select the application to enable.
Click Enable.
I hope this helps!!
